STEAM-RADIATO R.

SPECIFICATION forming part of Letters Patent N0. 422,541, dated March 4,1890.

` Application tiled March 8, 1888. Serial No. 266,585. (No model.)

.Be it known that I, GEORGE H. ROATH, a citizen of the United States,residing in Marietta, in the county of Lancaster and State ofPennsylvania, have invented certain Improvements in Steam-Radiators, ofwhich the following is a specification.

My invention relates to improvements in steam-radiators; and the objectof my improvement is to construct a radiator composed of a series otchambers located one above the other, so as to form a continuous slopingpassage from .the top to the bottom thereof, and in which the steam isfed directly into the upper chamber and discharged from the lower andits passage from chamber to chamber regulated. I accomplish theseobjects by the mechanism illustrated in the accompanying drawings, inwhich- Figure l is a vertical longitudinal section through the line a;a; of Fig. 2. Fig. 2 is an end view of my radiator. Fig. 3 is a hori-Zontal section through the line y y of Fig. l. Fig. 4t is a top view offour rectangular radiators joined together and furnished with steam bythe same supply-pipe; and Fig. 5 is a similar view of circular radiatorsjoined together, so as to receive steam in the same manner. t

The radiator is inclosed in an ornamental perforated frame or casing(not shown in the drawings) silnilar to those used for other 11adiatorsheretofore in use, and may be of any desirable or convenientconstruction.

In the drawings, A represents the shell, and B the supply-pipe, which is.connected with the top chamber C, and D the outlet-pipe through whichthe steam is discharged from the lower chamber C. Both pipes areprovided with stop-cocks b and d, respectively, and pass down throughthe opening G in the floor.

The partitions E, which divide the steamchambers from each other, slopefrom one end to the other of the shell, the upper partition incliningvdownward in one direction, the second in the opposite direction, and soon alternately throughout the series, the bottom of the laststeam-chamber inclining toward the outlet-opening. There is a space cleft between the lower end of each partition and the end wall of thecase which serves as a passage for the steam from each chamber to ihatnext below, as shown by the arrows in In the ends, opposite the lowerextremity of each partition, there is a short screw-bolt F, tapped intothe shell, which can be screwed in toward the ends of said partitions,and thereby regulate the passage of steam from one end to the other ofthe chambers. These bolts are made of such size as to greatly reduce theopenings between the lower ends of the partitions and the ends of theshell when screwed in against the ends of th'e partitions and the extentof such reduction is modified, as may be desired, in proportion to thedistance the bolts are screwed in. The operation of these bolts isillustrated in Fig. l.

Fig. 4t shows four square radiators united and supplied with steam fromone central feed-pipe H. Fig. 5 shows the arrangement of a number ofradiators L united to form a circle, the common feed-pipe I coming up inthe center. In other respects the radiators forming these groups areconstructed and operated in the same manner as the single one shown inFigs. 1, 2, and 3.

As the steam after it has entered the upper chamber G graduallycondens'es, it passes downward through the several chambers to theoutlet. The water of condensation fol. lows the same course as thatpursued by the steam and passes directly from the radiator through theoutlet-pipe to the boiler.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

l. In a radiator, the combination of a series of partitions extendingacross the shell, one above the other, the opposite ends of adjoiningpartitions sloping downward and having openings at the lower ends,devices for regulating the passage of steam through saidopenings, and asupply-pipe connected with the upper chamber and an outlet-pipe leadingfrom the lower, substantially as and for the purpose specified.

2. The combination, with the radiator and part-itions dividing the sameinto chambers and provided with openings at alternate ends which connectsaid chambers, of screwbolts tapped into the walls of the radiator atthe openings through the partitions, substantially as and for thepurpose specified.
